This Discovery kit features an all-inone open module CMWX1ZZABZ-091 (by Murata). The module is powered by an STM32L072CZ and an SX1276 transceiver. The transceiver features the LoRa® long-range modem, providing ultra-long-range spread spectrum communication and high interference immunity, minimizing current consumption. Since CMWX1ZZABZ-091 is an open module, user has access to all STM32L072 peripherals such as ADC, 16-bit timer, LP-UART, I2C, SPI and USB 2.0 FS (supporting BCD and LPM). The B-L072Z-LRWAN1 Discovery kit includes an ST-LINK/V2-1 embedded debug tool interface, LEDs, push-buttons, antenna, Arduino™ Uno V3 connectors and USB OTG connector in Micro-B format. The LoRaWAN™ stack is certified class A and C compliant. It is available inside the I-CUBE-LRWAN firmware package. Several examples, as an AT-command stack, are available to help users setting up a complete LoRaWAN™ node. System requirements • Windows® OS (XP, 7, 8, 10), Linux or macOS™ • USB Type-A to Micro-B cable Development toolchains • Keil® MDK-ARM(a) • IAR™ EWARM(a) • GCC-based IDEs including free SW4STM32 from AC6 • ARM® mbed™ online Demonstration software The demonstration software is preloaded in the STM32 Flash memory. The latest versions of the demonstration source code and associated documentation can be downloaded from the www.st.com/i-cube-lrwan webpage. a. On Windows 2/4 ® only.
